Removing the parent category from the breadcrumb nav

Does anyone know of a way (plugin or filter) that I can use to remove a category from the WP breadcrumb trail?

I have this appearance...

Home > Manufacturer > MyStuffInc > Product_Title

I want to remove "Manufacturer" from the breadcrumb but I'd prefer to keep it as a parent in the backend for ease of use when adding products.

Any ideas?
